Wow....just getting parts together for my 22 Creed and reading this has been very informative. Let me know if I'm off base but here is my synopsis of this thread:
First of all I am really surprised how many people went with faster twist barrels (7 and faster). The problem of blowing bullets up does not surprise me....I wouldn't have known, but not surprised based on experience I list below.
Faster twist barrels are hit and miss with blowing bullets apart. 8 Twist seems to be a much better choice for up to 88 grain bullets. I didn't read anything where the 95 grain bullets did not stabilize in an 8 twist....I would like to hear. I would bet 95's would be just fine in an 8 twist at my elevation (4600) and the high speeds.
I would think with such an overbore design, you should be able to get away with a slower twist barrel than the suggested by the manufacturer. In fact, I experienced that years ago with a 20BR and the 55 grain Berger bullets. Using an 8 twist would blow them apart occasionally, but never happened in my 9 twist and they were pretty much twins ballistically. I believe Berger stated an 8 was required. That's when I realized the bullet manufacturer's suggestion is more than likely not based on extreme speeds an overbore wildcat can produce. I'm sure I'm missing something more scientific but that's my opinion based on experience.
Thoughts?
